Abstract
A numerical controlled oscillator generating an output signal with a digital clock signal having a variable frequency is disclosed. The numerical oscillator is controlled by a programmable numerical value being subject to a transfer function and comprises a comparator configured to compare an output of the transfer function with a duty cycle register to generate the output signal.

A numerical controlled oscillator generating an output signal with a digital clock signal having a variable frequency, wherein the numerical oscillator is controlled by a programmable numerical value being subject to a transfer function and comprises a comparator configured to compare whether an output of the transfer function with a duty cycle register and to generate the output signal.
A method of generating a clock signal, comprising the steps of:
- providing an output signal with a digital clock signal having a variable frequency by a numerical controlled oscillator by subjecting a numerical value to a transfer function generating an output value,
- providing a duty cycle register coupled with a comparator, wherein the comparator compares the output value with the duty cycle register and generates the output signal when the value of the accumulator is equal or greater to the value of the duty cycle register.
